    Subject[PATCH 1/5] kselftests: dmabuf-heaps: Fix Makefile's inclusion of the kernel's usr/include dir
    Date
    Copied in from somewhere else, the makefile was including
    the kerne's usr/include dir, which caused the asm/ioctl.h file
    to be used.

    Unfortunately, that file has different values for _IOC_SIZEBITS
    and _IOC_WRITE than include/uapi/asm-generic/ioctl.h which then
    causes the _IOCW macros to give the wrong ioctl numbers,
    specifically for DMA_BUF_IOCTL_SYNC.

    This patch simply removes the extra include from the Makefile
